## CAVEATS

**paccheck** determines whether or not to read packages from *stdin* based on a naive check using [**isatty**(3)](/isatty/3.md).  If **paccheck** is called in an environment, such as a shell function or script being used in a pipe, where *stdin* is not connected to a terminal but does not contain packages to check, **paccheck** should be called with *stdin* closed.  For POSIX-compatible shells, this can be done with `"<&-"`.
